AAT3221 150mA NanopowerTM LDO Linear Regulator
The AAT3221 and AAT3222 PowerLinear NanoPower low dropout (LDO) linear regulators are ideal for portable applications where extended battery life is critical. These devices feature extremely low quiescent current, typically 1.1μA. Dropout voltage is also very low, typically less than 200mV at the maximum output current of 150mA. The AAT3221/2 have an enable pin feature which, when asserted, will enter the LDO regulator into shutdown mode, removing power from its load and offering extended power conservation capabilities for portable battery-powered applications. The AAT3221/2 have output short-circuit and over-current protection. In addition, the devices also have an over-temperature protection circuit, which will shut down the LDO regulator during extended over-current events. The devices are available with active high or active low enable input. The AAT3221 and AAT3222 are available in Pb-free, space-saving 5-pin SOT23 packages. The AAT3221 is also available in a Pb-free, 8-pin SC70JW package. The devices are rated over the -40°C to +85°C temperature range. Since only a small, 1μF ceramic output capacitor is recommended, often the only space used is that occupied by the AAT3221/2 itself. The AAT3221/2 provide a compact and cost-effective voltage conversion solution. The AAT3221 and AAT3222 are similar to the AAT3220, with the exception that they offer further power savings with an enable pin.
